Generations of British colonists grew up during a time when much of North America, especially the Northeast, engaged in war. Colonists knew war firsthand. In the eighteenth century, fighting was seasonal. Armies mobilized in the spring, fought in the summer, and retired to winter quarters in the fall. The British army imposed harsh discipline on its soldiers, who were drawn from the poorer classes, to ensure they did not step out of line during engagements. If they did, their officers would kill them. On the battlefield, armies dressed in bright uniforms to advertise their bravery and lack of fear. They stood in tight formation and exchanged volleys with the enemy. They often feared their officers more than the enemy.
